Film calls for independent investigation into the attacks on the World Trade Center and the Pentagon in 2001

Martin Sheen and Woody Harrelson are to star in a new film which questions the official story behind the 9/11 attacks.

'September Morn' supports some of the theories of the 'truther' movement, which has questioned the established version of the events of September 11, hinting at a government conspiracy.

The publicity note which the film is using, rather than give the usual idea of plot, reads: “We the people demand that the government revisits and initiates a thorough and independent investigation to the tragic events of 9/11. In the vein of 'Twelve Angry Men' this dramatic piece is set with a stellar and award winning cast.”
